Global Optimization of Redescending Robust Estimators

Table 6

Circles and corresponding parameters obtained with the Geman–McClure estimator computed by GO: for each solution (Solution No.), x_c and y_c are the coordinates of the center, r the radius, L the circumference length, No. Points: the number of points generated for the circle, and P₁, P₂, P₃ are the circle parameters. Circle No. is the corresponding circle number in Table 3.
